Application filed June 12,

the cross footing machine disclosed in my Patent No. 1,27OA71, granted June 25, 1918.

The object of my present invention is to provide a machine adapted to perform horizontal and vertical addition, employing a so-called jumping totalizer therefor, and to so arrange this machine that said jumping totalizer may be employed to calculate in a variety of tables. I

Another object of my invention is to pro vide a cross footing machine having a sin- .gle jumping decimal carriage and having means to calculate plurality of cross footings simultaneously.

Another object of my invention is to provide an improved mechanism adapted to perform the above recited operations. These and other objects of my invention will be hereinafter described'and claimed.

1 have provided a typewriter having a -Wahl cross-footing calculating mechanism attached thereto. However, the jumping truck, which carries the cross footing totalizer in the'structure disclosed in my cited application, instead of having a single total izer mounted thereon, carries a plurality of totalizers. This truck is held in its normal position by a spring and is picked up by the main carriage of the typewriter at the calculating Zones and automatically disconnected therefrom. In the structure shown in my prior patent, the points of pickup and disconnection are invariable throughout a single traverse of the main carriage of the typewriter. This is for the reason that in said structure I have shown but a single totalizer on the cross truck. In the invention disclosed in my present application, I have shown a plurality of totalizers on the cross truck, and in order to calculate in these various totalizers, it becomes necessary to change the point of disconnection of the cross trucklfrom the main truck as said main truck reaches different points of Specification of Letters Patent.

its travel. 1 therefore have provided a set of cams on the maintruck and these cams through suitable mechanism control the point of disconnection of the cross truck..

A further difference in my herein described invention from the invention shown in my cited patent lies in the fact that in my prior structure, the vertical totalizers themselves carried the connecting locations which served to pick up the cross truck. As will be seen in the description of my present invent on, it is not desirable to employ this particular form of pickup in connection with the use of a plurality of totalizers on the cross truck, and 1 therefore have pro vided a series of independently locatable pick-ups on the main truck.

My invention may be best understood by reference to the accompanying drawings, of wh1ch Figure 1 is a front elevation of a calculating machine employing my invention.

Figs. 7, 8, 9, 10, 11 and 12 are diagrammatic views showing the cooperation of the vertical and cross master wheels with their then associated totalizers.

Fig. 13 is a perspective View of the bar having but one connecting location.

Referring to Figs. 1 and 2, 10 represents the frame work of the typewriter on which is mounted a truck 11, which is connected to the printing carriage 12 of the typewriter and progresses step by step therewith. On this truck 11, which I shall hereinafter call the vertical truck, are mounted the vertical totalizers 18, 14, 15, 16, 17 and 18. Supported by the framework of the typewriter is the cross truck 19 which is adapted to reciprocate in suitable guides 20 and is held in its normal position by a spring 21, one end 22 of which is fastened to the frame work 10, and'the other end is fastened to the truck 19. The spring 21 is passed around the pulley 23 which is mounted on a stud screw 24 in the frame work 10. On the cross truck 19 are mounted cross totalizers 25, 26 and 27.

The typewriter is provided with a set of numeral keys 28 which are connected by pull rods 29 to the actuating mechanism 30.

This actuating mechanism is in two parts and serves to rotate a vertical master wheel 31 and a cross master wheel 32 a differential amount according to the particular numeral key 28 depressed. The vertical master wheel 31 serves to enter numbers in any of the vertical totalizers 13 to 18 both inclusive, and the cross master wheel 32 serves to enter numbers into any of the cross totalizers 25, 26, and 27. Since the mechanism by which the differential rotation of the master wheels is accomplished is thoroughly described in my cited patent, it is not necessary to describe the same here, since this differential mechanism forms no part of my present invention. The direction of rotation of the vertical master wheel 31 is controlled by the handle 33 and according to the setting of this handle the vertical master wheel may be caused to add, subtract or not rotate at all upon the depression of any of the numeral keys 28.

Correspondingly the direction of rotation of the cross master wheel 32 may be con trolled by the setting of the handle 34 which may be set in any of three positions thereby to determine that the cross master wheel shall either add, subtract or not rotate at all upon the depression of any of the numeral keys 28. The cross master wheel 32 may be also under control of the automatic gear shift which is operated by the cams 3o, 36 and-3T which are attached to the vertical totalizers 14, 16 and 18, respectively, and serve to operate a roller 38 mounted on an arm on the shaft 39 rotatably mounted in the frame work 10. A handle 40 by its position serves to determine whether the cross master wheel 32 shall be under control of the handle 34 or of the automatic gear shift controlled by the cams 35, 36 and lVhen the handle 10 is in the position shown in Fig. 1, the automatic gear shift is controlled by the cams. lVhen the said handle is shifted to its upper position, the automatic control by the cams 35, 36 and 37 is ineffec ive and the cross mast-er wheel 32 is controlled by the handle The automatic control for the cross master wheel 32 may be used to determine that said master wheel shall add, sub tract or not operate upon the depression of any numeral key 28, this selection being accomplished by either the absence of the cam 35 or by determining the particular distance to which the said cam 35 depresses the roller 38.

In addition to the various gear shifts just mentioned, the machine has a common reversing or rror lever 11 which controls both the vertical master wheel 31 or cross master wheel 32 and this error lever when operated serves to throw both of said master wheels into the reverse of their former condition. This is for the purpose of correcting errors.

All these gear shifts have been thoroughly described in my cited. patent and it is not necessary in this application to go into the mechanism by which these various functions are accomplished.

I shall now enter upon a description of mechanism which is peculiar to my present invention.

As before noted, the cross truck 19 is adapted to reciprocate in ways 20 and is held in its normal position by a spring 21. l\;[ounted on this truck is a pickup beam 412 (Fig. 1) having thereon a latch 43 which is adapted to be engaged by the connecting stops 14; and 45. I have given numbers to these stops as associated with but one particular group of totalizers. A description of the stops associated with one particular group of totalizers will serve as a description of similar stops associated with the other groups. on a bar 16 which is adapted to slide in a slot d7 cut in the lower part of the truck 11. l fhe bar 416 has in it a slot 48 which is adapted to engage the lower part of the totalizer side plate 19 and thus the entire bar, and its associated stops 4A and 15, is held in its proper position by the locating of the totalizer of which the plate 419 is a part. Slidably mounted in the pickup beam -12 is a pin .30 which is adapted to slide in a slot 51 in a plate 52 mounted rigid with the frame work. it one end of the slot 51 is a cam surface which engage the pin 50, and thereby disconnects the latch from the particular connecting location or stop on the vertical truck with which said latch may be at that time engaged.

Owing to the fact that there is not one totalizer but a plurality of them on the cross truck, it is necessary to disengage the pickup beam 12 from its connecting location on the vertical truck 11 not at one definite point in the travel of said pickup beam 42, but at a plurality of points in order to bring the totalizers 25, 26 and 27 mounted on the cross truck 19 into their proper relation with the corr spending vertical totalizers 13 to 18 inclusive. riccordingly I have pivoted on the plate 52 at 54, a lever 55 which is held in a normal position against a stop 56 by a spring 57. Said lever is normally in the position shown in Fig. 4., but at certain points in the travel of the main truck 11, may be raised into the position shown in Fig. 5. It is to be noted that when in this The stops i l and 45 are projections fective on the pin 50 mounted in the pickup beam 42, but that a cam surface 58 on the lever 55 will intercept the pin 50 before the same reaches the cam surface 53 and by its action disconnect the latch 43 from the connecting locations 44 or 45 with which it may then be engaged and'the cross truck 19 will accordingly be drawn back by the spring 21 to its normal position. In addition to thelever 55, 1 have shown a second lever 59 having a cam surface 60 held 1n its normal position by the spring 61 against the stop pin 62, and it will be evident from in spection of Fig. 5- that if the lever 59 is raised into the position shown in said figure before the pin 50 passes said lever, that both the cam surface 53 and the cam surface 58 will be ineffective to disconnect the pickup beam fromthe vertical truck, for the cam surface 60 by contact with the pin 50 will cause this disconnection.

- I shall now describe the means by which the levers 55 and 59 are operated. Rotatably mounted onthe shaft 39 is a lever 64 having "mountedon the'e'nd 65 thereof a roller 66,

and pivoted on the end 67 thereof a link 68. The link 68 has mounted in its end a pin 69 which is guided in a slot 70 in the plate 52. 'Mounted in the link 68 is a pin 71 which is adapted to contact with an arm 72 of the lever 55, and thereby rotate said lever about its pivot 54. Similarly a second pin 73 contacts with an arm 74 on the lever 59, which is pivoted on the plate 52 at 75,

and rotates said lever 59 about its pivot 75. The position of the levers 55 and 59 is determined by the presencev or absence of a cam 76 on any of the vertical totalizers 13 to 18 inclusive. The cam 7 6 has a nose 77 which is adapted to contact with and depress the roller66 when the totalizer 'on which said cam is mounted is in its units position. Said nose 77 is long enough to hold said roller 66 depressed while the cross-footing totalizer jumps to its sub-units position. From what has gone before it is apparent that depres sion' of the roller 66 will result in the throwing of the levers and 59 into the position shown in Fi 5, and in case the pin 7 50 happensto be in the position shown in either of the positions 50 or 50", said pin will be immediately acted on by either the cam surface 58 or the cam surface 60. o thus can formulate the general rule that in the absence of the cam 7 6, the pickup beam 42 will be disconnected from the vertical truckwhen the pin 50 reaches the cam surface 53. The presence of the cam 76, however, will serve to disconnect the pin either by the cam surface 58 or the cam surface 60 and which one of these cam surfaces will be effectual is determined by the position of the connecting locations 44 and 45.

Mounted on' the plate 52 is an auxiliary rality of holes being provided in the plate '10 I 52 in order to permit of the adjustment of the auxiliary plate 78 to take care of variations in the sizes of the totalizers which may be used on the cross truck 19. On theauxiliary plate 78 is pivoted at 83 a latch 84 held by a spring 85 in a normal position. This position is determined by having astud rigidly mounted in the latch 84 and to which the spring 85 is attached projecting through said latch into the slot 87 in the auxiliary plate 78. The function of the latch 84 is to supplement the tension of the spring 88, Fig. 4, which serves to hold the pickup beam 42 in a position to engage any of the connecting locations 44, 45, etc. When the cross truck is at rest in its normal position, the

typewriter carriage and its connecting locations may be tabulated to the left. The connecting locations will then engage the latch 43 with somewhat of a jar and it is advisable to have an extra spring tension to prevent the disengaging of said latch from the connecting locations. On the other hand, when the latch 43 is disconnected from the corn necting locations by reason of contact of the pin 50 with any of the cam surfaces 53, 58 and 60, it is desirable that the force holding the latch 43 into the connecting locations be small. it will be observed that the upper surface of the lever 84 forms a continnation of the lower surface of the long slot 89 in the plate 52. This is for the purpose of preventing the accidental disengagement of the latch 43 from any of the connecting locations, said slot 89 having a width approximately equal to the diameter of the pin 50. The lower portion of the slot 89 has a recess 90 opposite the lever 84-, also a recess 91 opposite the lever 59, and a. recess 92 opposite the lever 55.

It will be observed that when the two levers 55 and 59 are in their normal positions, as shown in Fig. 4, the upper sides of these levers form a continuation of the lower line of the slot 89. However. when these levers are raised so as to cause the disconnection of the pin 50 as shown in Fig. then the recess 91 and the recess 92 are uncovered, and it is possible for the cam sur faces associated with said levers 55 and 59 to act effectually on the pin 50 and thereby disconnect the pickup beam 42 from its then engaged connecting location.

Referring to Fig. 3, the bar 46, shown therein. has two connecting locations 44 and 45, rigid with said bar. This arrangement is not necessary in all cases, but depends upon the arrangement and capacities of the totalizers 25, 26 and 27 on the cross truck.

In Figs. 7 and 13, I have shown an alternatire construction which the bar 93 has a single connecting loc 'on 94!- mounted thereon 11K, nas a 97 and 93 in the ba 9 adapted to receive t i n vertical tota e slots 95, 96,

inch aria th- 9? and ical truck 11. i shall now describe a L tion ot a form oi arrangecross totalizer when eng ged with their respec ive masterwheels.

In Fig. i, t rranged that lag locations are al master wheel 31 the vertical totalniaster wheel 32 ii" the he cross totalizcr When the r olace oi the tota 1? has been reacneu the pickup beam i c trom the is connected to When in this connecting location i i the succeeding location position the ve c tcriug number? and the cross subtracting numbers "from the cross totalizer L5. This arrangement is shown in F' Coming now to the next group of vertical totalizers, Fig. 9 shows the vertical master wheel 31 entering numbers in the vertical totalizcr and the cross master wheel 32 simultaneously entering numbers into the cross totalizer 2", the connecting location in this case being the side plate of the vertical totalizer 16. At or the number has been entered into the vertical totalizer 15 and the cross totalizer 26, the pickup beam is disconnected and the mechanis a assumes the position shown in Fig. 10. In this figure the numbers are being entered into the vertical totalizer 16 and subtracted from the cross totalizer 26. The vertical truck is then moved to the left and the vertical master wheel 31 comes into engagement with the vertical totalizer 17 and the cross master wneel 32 into engagement with the cross totalizer 27, heels on the side plates of the vertical totalizers 17 and 18 being used for the connecting locations, as is shown in my cited patent. The vertical truck passes on to the next location and the vertical master wheel engages the totalizer 18 and the cross master wheel the cross totalizer 27. Since the relation of the cross truck 19 to the vertical totalizers 17 and 18 when performing the calculation shown in Figs. 11 and 12 is the same as when the machine is in its normal position, it is not necessary to provide any additional connecting locations for these two positions, the heels on the right side plates oil the totalizers 17 and 18 serving to pick up the pickup beam.

It is obvious by the arrangement herein shown that the cross totalizers 25, 26 and 27 need not calculate in the same tables. For instance, I can have the vertical group 13 and l lcalculate in weights, the vertical group 15 d 16 calculate in English money nd the vertical group 17 and 1S calculate American money. Corrcspoudingly, the cross totalizer would calculate in weights, the cross totalizer 26 would calculate in English money, and the cross totalizer 27 would calculate "a American money. While in the arrangement given I have shown the vertical totalizers in two groups and a single cross totaiizer cooperating with each of these groups, this precise arrangement is by no means necessary, since by reason of being able to change both the point of connection as determined by the position of the connecting locations 1 1 and -15 and the point of disconnection as determined by the action of the cams 53, 58 and 60. I am enabled to get a great variety of difi'erent arrange ments and combinations between the vertical and cross totalizers. It is not necessary in this place to give an extended list of these combinations, since they will be apparent to those skilled in the art.

While I have shown each cross totalizer calcu with the group of vertical totaliz rs which are placed adjacent to each other, c. 92, the cross totalizer serving to cal ,tlnlTQ numbers entered into the vertical ti" alizers 13 and 1 1, the cross totalizer 26 serving to cross toot numbers entered into the vertical totalizers 15 and 16, etc., it is evident that this arran ement is not necesand that any one or the cross totalizers may calculate numbers written in columns which are not adjacent to each other. A, set-up of the machine to accomplish this can evidently be made by re-adjusting the connectin locations -14 and 45, and also b provic ,ng suitable earns 76 on the totalizer to change the disconnecting point. It is also true that the number of totalizers in a vertical group i not limited to two, since there may be more than two; in fact, the only limit to the number of vertical t0- talizers which will calculate in the main totalizer on the cross truck is the available space on the vertical truck.

I also wish to call attention to the fact that the lever (it in my present application, in addition to governing the levers and 59 has also the same function as the lever numbered 4278' in my cited patent. Reference thereto will disclose that said lever 478 controls an interlock between the jumping topositions. There'is one position in which it calculating machine is unlocked.

.ferent tables.

is not'affected by any cam. There is a second position in which it rests on the surface of the cam 76, and there is a third position. in which it contacts with the nose 7'? of the cam 76. In the first of these positions, the g In the second, the calculating machine is locked except when the cross truck is picked up and displaced from its normal position. In the third of these positions the lock referred to still persists, but in addition, the levers 55 and 5.9 are displaced into the position shown in Fig. 5. I v

i In some of theclaims I have used the expression totalizers calculating in two dif- For the sake of brevity, I have used this term to denote also totalizers which calculate in the same table, buthave adifferent spacing relative to the number wheels. For instance, I wish to be understood that 1 consider a tot-alizer spacing 999 999 99" and a. totalizer spacing 999999 99 as the mechanical equivalents of I a totalizer calculating in one table as a vertical totalizer and a totalizer calculating in a different tableas a cross totalizer.

For the sake of brevity in the claims I have used the term totalizers calculating in two tables to denote either totalizers which compute 1n twodifferent tables, such for in- V stance, as Zt'tOtLllZBI' computing in American 'money which is to thebase 10, and a totaling decimal carriage can cross foot in a variety of tables simultaneously. lhere have been machines proposed which, while havingbut a single jumping carriage, could compute in difierent tables during a single run ofthe main carriage, but in these machines it was necessary to first clear the cross totalizer of the amount computed 1n one table before entering the amount to be computed in a second table. Obviously with my machine, a number in one table may be accumulated in the totalizer 25 and without clearing said totalizer, a number in a different table may be accumulated in a totalizer 26. After all the accumulation has been done these totalizersmay then be separately cleared so that the single jumping truck may be said to permit the simultaneous cross computation of the amountsin the different tables, I believe this arrangement is new with me and I wish to claim the same broadly.

Many changes and, variations may be made in the precise structure herein described since I claim:

In a calculating machine, the combination of totalizer actuating mechanism, a series of vertical totalizers adapted to compute in different tables, a traveling member serving as a support "for said totalizers, a truck adapted to be intermittently connected to said traveling member, a plurality of cross totalizers of different tables mounted on said truck, and means to bring said vertical and cross totalizers into the proper decimal relation so that when a number is entered by said actuating mechanism into a vertical totalizer computing in one table, the same number shall be simultaneously entered into the cross totalizer computing in the same table.

27. In a calculating machine, the combination of a traveling member, a decimal carriage adapted to be intermittently connected to and disconnected from said traveling member, a set of numeral keys, a lock for said numeral l-zeys, shiftable means to vary the point oi disconnection of said jumping decimal carriage from said traveling mem ber, and a single lever jointly controlling said loci: and said shift-able disconnecting means.

28. In a calculating machine, the combina tion of a traveling member, a decimal carriage adapted to be intermittently connected to and disconnected from said traveling iember, a set or numeral keys, a lock for said numeral keys, shiftable means to vary the point of disconnection of said jumping carriage from said traveling member, and a lever controlled by said member to operate said lock and shiftable means.

29. In a calculating machine, the combina tion of a traveling member, a decimal carriage adapted to be intermittently connected to and oisconnected from said traveling member, a set of numeral keys, a lock for said numeral keys, shiftable means to vary the point of disconnection of said jumping carriage from said traveling member, and a lever controlled by the cam on said traveling member to control jointly said lock and said shit'table means. i

30. In a calculating machine, the combina tion of a traveling member, a jumping decimal carriage adapted to be connected intermittently to said traveling member, a shiftable disconnecting means to determine the point of disconnection of said jumping carriage from said traveling member and means under control of said traveling member to determine the position of said disconnecting means.

31. In a calculating machine, the combination of a traveling member, a series of adjustable connecting lugs slidably mounted on said traveling member, a totalizer mounted on said traveling member, and connections between said totalizer and said connecting lugs to hold the same in a fixed position relative to each other, whereby the adjusting of said totalizer relative to said traveling member will simultaneously adjust the attached connecting lugs.

32. In a calculating machine, the combination of a traveling member, a groove in said traveling member, a connecting lug mounted. in said groove, a totalizer mounted on said traveling member, and an adjustment be tween said totalizer and said connecting lug whereby the latter may be displaced relative to the first and held by the totalizer in its displaced position.

In witness whereof, I have hereunto signed my name this ninth day of June, 1916.
